Carbo - hydrate. Glucose is a common carbohydrate that will show up again and again as we discuss cell chemistry: its formula is C6H12O6. Table sugar, sucrose, is two single sugars bound together: a disaccharide simple sugar. Sugars can be anything from a single sugar molecule up to several bound together.
The two sides of the DNA molecule are Deoxyribose and phosphate these two molecules are what make up the two sides of DNA.
DNA had two sides, or strands, and that these strands were twisted together like a twisted ladder -- the double helix. The sides of the ladder comprise the sugar-phosphate portions of adjacent nucleotides bonded together.
